So what's wrong?

What problem are you having? Your code (classes, methods, variables) has words from another language and that makes it difficult to understand, so any additional information you can provide would help the people on the forum to understand your problem.

Luck,

Chris S.Difficult? This is Mission Impossible, not Mission Difficult. Difficult should be easy.

From my javabook I got pieces of the code, and now when I tried to puzzle them together it doesn't work at all. I'm afraid to touch the code to much because the book schould be right!
So I don't know how to continue this.
My editor tells me that some packages doesnt exist, although they does, and "cannot find symbol". I import awt, util and further, and the editors says that it's an unused import.

I can coby the text from a debug.
